Free online USDZ to 3MF converter

Source format: USDZ

USDZ is a packaged 3D file format based on Pixar’s USD (Universal Scene Description). It is commonly used in AR workflows, especially on Apple devices, because it can store a 3D model together with materials, textures, and scene data in a single archive. Designers, 3D artists, product visualization teams, and app developers use USDZ for augmented reality previews, e-commerce product viewing, and sharing lightweight 3D assets that open directly in supported viewers.

USDZ is convenient for distribution, but it is not always the best format for 3D printing or manufacturing workflows, because those usually need a mesh-focused format with broader slicer support.

Target format: 3MF

3MF is a modern 3D Manufacturing Format designed for additive manufacturing and 3D printing. It can store geometry, units, colors, materials, textures, and print-specific metadata in a compact package. Compared with older formats such as STL, 3MF is often better because it preserves units, supports richer model data, and reduces ambiguity when importing into slicers.

3MF is widely supported by 3D printing software and slicers, making it a strong choice when the goal is to prepare a model for printing rather than AR viewing.

How to perform the conversion

The most reliable way to convert USDZ to 3MF is to use a 3D modeling application that can import USDZ or USD-based files and export 3MF. A practical workflow is:

1. Open the USDZ file in a compatible desktop application such as Blender, Apple Reality Converter, or another USD-capable 3D tool.
2. Check the imported model for scale, orientation, and materials. USDZ files are often created for viewing, so the model may need cleanup before printing.
3. If needed, convert or unpack the USDZ into a supported USD scene first, then import that scene into your 3D tool.
4. Export the model as 3MF using the application’s export function, for example File → Export → 3MF.
5. Open the resulting .3mf file in your slicer or 3D printing software to verify that the geometry, units, and orientation are correct.

If you want a quick browser-based option, you can also convert the file on 101convert.com for free without installing any software.

Notes on quality, compatibility, or limitations

USDZ to 3MF is not always a perfect one-to-one conversion. USDZ is optimized for AR presentation, while 3MF is optimized for manufacturing. During conversion, some features may be lost or simplified, especially animation, scene hierarchy, lighting, and advanced USD material effects. For 3D printing, this is usually acceptable because slicers mainly need a clean, watertight mesh.

Also note that 3MF support varies by software. Some tools preserve colors and textures well, while others export only the mesh. Always inspect the output in a slicer or 3D viewer before printing. If the model is intended for print, you may need to repair non-manifold geometry, fix normals, or merge separate parts after conversion.
